Resolution: Fixed
> Specialization of property API for PK
> -------------------------------------
>
> Key: CAY-2604
> URL: https://issues.apache.org/jira/browse/CAY-2604
> Project: Cayenne
> Issue Type: Improvement
> Components: cgen
> Reporter: Nikita Timofeev
> Assignee: Nikita Timofeev
> Priority: Major
> Fix For: 4.2.M1
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Properties generated for PK in 4.1 has issues (see CAY-2565), so we need some
> logic to deal with them.
> Instead of using DbPath directly we can make special type of {{Property}}
> (probably {{IdProperty}}) to make them usable in all cases.
> Required cases to handle:
> - compatibility with {{dot()}} operator
> - in-memory sorting
> - in-memory evaluation
> My approach is to use special name {{"@id"}} as path for PK. Limitation - it
> will be unusable with compound PKs.
